Descriptions
Multiple integer overflows in the evbuffer API in Libevent 2.0.x before 2.0.22 and 2.1.x before 2.1.5-beta allow context-dependent attackers to cause a denial of service or possibly have other unspecified impact via "insanely large inputs" to the (1) evbuffer_add, (2) evbuffer_prepend, (3) evbuffer_expand, (4) exbuffer_reserve_space, or (5) evbuffer_read function, which triggers a heap-based buffer overflow or an infinite loop. NOTE: this identifier was SPLIT from CVE-2014-6272 per ADT3 due to different affected versions.
Vulnerabilidad de desbordamientos de entero múltiple en la API evbuffer en Libevent 2.0.x en versiones anteriores a 2.0.22 y 2.1.x en versiones anteriores a 2.1.5-beta, permite a atacantes dependientes del contexto causar una denegación de servicio o posiblemente tener otro impacto no especificado a través de 'entradas increíblemente grandes' en la función (1) evbuffer_add, (2) evbuffer_prepend, (3) evbuffer_expand, (4) exbuffer_reserve_space o (5) evbuffer_read, lo que desencadena un desbordamiento de buffer basado en memoria dinámica o un bucle infinito. NOTA: este identificador ha sido SEPARADO de CVE-2014-6272 por ADT3 debido a las diferentes versiones afectadas.
